Nematode parasites of groundnut.

Groundnut is the common name for several leguminous plant species producing seeds that mature underground, including Bambara groundnut (Vigna subterranea), Hausa groundnut (Macrotyloma geocarpum) and peanut (Arachis spp.). This chapter describes the nematode parasites of groundnut, including Meloidogyne spp., Pratylenchus brachyurus, Belonolaimus longicaudatus, Aphelenchoides arachidis, Tylenchorhynchus brevilineatus [Bitylenchus brevilineatus] and Ditylenchus africanus. Information is given on their infection and histopathology, symptoms of damage, biological races, survival and means of dissemination, environmental factors affecting parasitism, disease complexes, economic importance and population damage threshold levels, and management measures, including host resistance, cultural, chemical, biological control methods.
